Had our first home power outage since owning the Lightning, so I pulled out the 14-30 cable and plugged the truck into our generator cutover circuit.
We'd spent a good share of the day driving, and when the power went out around 5pm I had 33% charge.

The manual cutover to the Lightning was seamless, though I had gone through and pulled the plugs on our 3 chest freezers, and turned off the subpanel to our barn,to minimize the initial load.
We were without grid power until a text from the utility came just before 8pm.
During that time I was trying to use the PPO app and truck display to gather actual draw, and that I must say was the biggest disappointment. It'd be really nice to have actual power draw figures and/ or graphs with a summary of the session once complete.
Based on the decrease of about 4% battery charge (and figuring roughly 80% efficiency on the inverter) I'd say we used an avg of around 1.2kwh for the 3 hours.

Overall I'm thrilled to have what looks to be a solid 2 to 3 days of backup power available in the event of an outage (as long as I'm 90% charged when the grid dies!)
Just add to the Ford wishlist an OTA / app update that gives us some better data!

What does your inlet and panel look like? This is the set up I would like to get installed but I keep reading conflicting things about bonded neutrals and GFCI tripping, it’s not clear to me what I need to tell an electrician.

I'll snap some pics of the main and sub panels.
I'm no electrician, but the installation I have in place thanks to my local electrician, seems to work fine.
I had no issues with GFCI or arc-fault circuits while on the generator circuit.

Ok, Here's a little more info on my generator hookup.
The pic shows the 100amp sub panel attached to my home's main 200 amp panel.
The 30 amp breaker marked is connected via AWG 10/4 cabling to an L14-30 outlet outside the house.
To cut over, I do the following:
1. Flip the 200amp main breaker off.
2. Plug one end of my 20' 10/4 extension cable into the house outlet and the other end into the Lightning's 30 amp 240v bed outlet.
3. Power on the truck and enable the bed circuits via Pro Power Onboard.
4. Flip on the 30amp generator breaker (labeled in the pic), and Let there be LIGHTS!

Did you compare the in-truck and FordPass power draw at the same time? They both seem to be providing instantaneous draw for each circuit.

This E-Hermes video goes is right on topic. They've done some fearless Lightning road tripping, too:

No doubt that what you did will function as you described. However, you and your electrician may have some liability issues. Step #1 is not something you should have to ‘remember‘ to do, at the very least, there should be an interlock device to prevent accidentally turning on the backup power before disconnecting the main. There is another thread here that shows a simple slide plate interlock that accomplishes this at very little cost. Since this is a sub panel, you avoided the ground fault problem others have mentioned, likely your main panel has the neutral bond there.
